Other names :
Neryl acetate ; (2Z)-3,7-dimethylocta-2,6-dienyl acetate ; Nerol acetate ; Neryl ethanoate ; Acetic acid neryl ester ; (Z)-geranyl acetate
Volatility :
Heart
Uses in perfumery :
Neryl acetate is used in neroli and rose floral accords to bring a fruity-floral nuance.
Natural availability :
Neryl acetate is present in several citrus fruits and Petitgrain Bigarade EO, from which it can be extracted to obtain natural Neryl acetate. Although its price is high as it is present in small quantities in its natural state.
Year of discovery :
Data not available.
Other comments :
Seeing it detection threshold Geranyl acetate is much more powerful than Neryl acetate.
Price Range :
€€
Stability :
acetates may form acetic acid through time

Synthesis route :
Neryl acetate can be synthesized from Nerol by an esterification reaction using acetic acid or acetic anhydride, or from Myrcene, in two stages: an addition reaction with acid hydrochloric acid, catalysed by copper chloride II, followed by an acetolysis reaction using sodium ethanoate and a base such as triethylamine. This reaction allows to obtain both (Z) Neryl acetate and (E) Geranyl acetate, two diastereoisomers.
Synthesis precursor :
Neryl acetate is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
May contain traces of Geranyl acetate. Both diastereoisomers have a similar smell, although more terpenic, less powerful and lemony for Neryl acetate.
Linalyl acetate, Terpenyl acetate and Isobornyl acetate are isomers of Neryl acetate.
However, Linalyl acetate and Terpenyl acetate are reminiscent of Bergamot EO and Isobornyl acetate of pine.
